Benefits of technology

The patent aims to maximize the display device's aperture ratio by reducing the size of the light blocking member. By positioning a portion of the white filter or blue filter, as well as their corresponding sub-pixel electrodes, between the red filter and green filter and their corresponding sub-pixel electrodes, color mixing is minimized or prevented. This results in acceptable image quality for the display device.

Problems solved by technology

Nevertheless, a large size of the light blocking members may negatively affect an aperture ratio associated with the reflective liquid crystal display device.

Embodiment Construction

[0065]Embodiments are described with reference to the accompanying drawings, wherein like reference numerals may refer to like elements throughout. The embodiments may have different forms and should not be construed as being limited to the descriptions set forth herein.

[0066]Although the terms “first”, “second”, etc. may be used herein to describe various elements, these elements should not be limited by these terms. These terms may be used to distinguish one element from another element. Thus, a first element recited in this application may be termed a second element without departing from embodiments. The description of an element as a “first” element may not require or imply the presence of a second element or other elements. The terms “first”, “second”, etc. may also be used to differentiate different categories or sets of elements. For conciseness, the terms “first”, “second”, etc. may represent “first-category (or first-set)”, “second-category (or second-set)”, etc., respecti...

Abstract

A display device may include a first layer, a passivation layer, and a pixel. The passivation layer may overlap the first layer and may include a first passivation portion and a second passivation portion. The pixel may include a first-color filter, a first-color-corresponding electrode, a second-color filter, and a second-color-corresponding electrode. The first-color-corresponding electrode may overlap the first-color filter and may be positioned between the first layer and the first passivation portion. The second-color-corresponding electrode may overlap the second-color filter. The second passivation portion may be positioned between the first layer and the second-color-corresponding electrode.

Description

CROSS-REFERENCE TO RELATED APPLICATION[0001]This application claims priority to and benefit from Korean Patent Application No. 10-2015-0130692 filed on Sep. 16, 2016 in the Korean Intellectual Property Office; the contents of the Korean Patent Application are herein incorporated by reference.BACKGROUND[0002]1. Field[0003]The technical field relates to, a display device, such as a reflective display device.[0004]2. Description of the Related Art[0005]A display device, such as a liquid crystal display device, may include a liquid crystal display (LCD) panel for controlling light transmission and may include a backlight assembly for supplying light to the LCD panel.[0006]A reflective liquid crystal display device may control transmission of light by reflecting natural light or ambient artificial light using a reflecting plate without requiring a separate backlight assembly. Therefore, a reflective liquid crystal display device may be lighter in weight and requires less power consumptio...
